Synthesis of N-acyl-.GAMMA.-D-glutamyl peptide derivatives containing a C-terminal small fragment of cholecystokinin and their effects on gastric secretion.
摘要:
制备了含有胆囊收缩素 C 端小片段的 N-酰基-γ-D-谷氨酰肽衍生物,并研究了它们对胃液分泌的影响。PhCO-D-Glu(Phe-NH2)-NPr2和PhCO-D-Glu(Asp-Phe-NH2)-NPr2抑制胃液分泌,而PhCO-D-Glu(Met-Asp-Phe-NH2)-NPr2和PhCO-D-Glu(Trp-Met-Asp-Phe-NH2)-NPr2刺激胃液分泌。PhCO-D-Glu(Phe-NH2)-NPr2 N 端酰基功能的替代影响了其活性。研究发现,Z-D-Glu(Phe-NH2)-NPr2、4-氯苯甲酰基-D-Glu-(Phe-NH2)-NPr2 和异烟酰基-D-Glu(Phe-NH2)-NPr2 对胃液分泌的抑制活性比丙谷胺(PhCO-DL-Glu-NPr2)更强。
